to satisfy the balance between the robustness and the imperceptivity, the hvs model is used to adaptively adjust the watermark embedding strength.
为了满足鲁棒性和不可感知性之间的平衡,使用人类视觉模型自适应地调节水印的嵌入强度。
the hvs model is based on the computation of the noise visibility function (nvf) and embed at the texture and edge region stronger embedded watermarks.
模型基于噪声可见性函数(nvf)的计算来决定水印嵌入强度,使水印更多的嵌入到图像的纹理和边缘区域。
to make the compromise between the robustness and the imperceptivity, a new 3-d hvs model is reconstructed and used to adjust the embedding strength.
为了平衡鲁棒性和不可感知性,新的适用于3维的人类视觉模型被重构并用于调整水印的嵌入强度。
